Relationship between Cytochrome P450 1A2 Gene Polymorphism and Susceptibility to Chronic Obstructive Pulmonary Disease / 中国康复理论与实践

@#Objective To investigate the relationship between cytochrome P450 1A2 (CYP1A2) gene polymorphism and susceptibility to chronic obstructive pulmonary disease (COPD). Methods CYP1A2 gene polymorphisms in 100 COPD cases and 100 healthy controls were tested with polymerase chain reaction- restriction fragment length polymorphism (PCR- RELP). Results Genotype frequencies of 4 SNPs in both the COPD and control groups were in accordance with Hardy-Weinberg equilibrium (P>0.05). There was significant difference between the COPD and control groups in genotype and allele frequencies of 1D and 1F (P<0.05), but not of 1C and 1E (P>0.05). Conclusion CYP1A2*1D and CYP1A2*1F polymorphisms may play an important role in the development of COPD.
